An invoice went out for the wrong amount. Or goods came back. Or a supplier billed you for something you never received. The instinct is to edit the invoice, and it is the wrong instinct: an issued invoice is a document you have already given someone, and quietly changing it destroys the audit trail on both sides.
There are three correct instruments, and they do different jobs.
The three, side by side
| Credit note | Refund | Debit note | |
|---|---|---|---|
| Issued by | The seller | The seller | The buyer |
| Says | “I owe you this back” | “Here is the money back” | “You owe me this back” |
| Money moves | No | Yes | No |
| Creates | A balance the customer can spend | A cash outflow | A claim against a supplier |
| Typical use | Over-billing, returns, agreed discounts | Customer wants the cash back | Supplier over-billed you |
The distinction that matters most: a credit note is not a refund. A credit note is an acknowledgement that you owe something back. A refund is the act of returning it. One can lead to the other, and frequently does not, because most customers would rather set the credit against their next invoice.
Credit notes
A credit note is the seller’s correction document. It has its own number, its own date and its own balance, and it exists alongside the original invoice rather than replacing it.
When to raise one
- You invoiced too much: wrong quantity, wrong rate, a line that should not have been there.
- Goods were returned.
- You agreed a discount or a goodwill gesture after invoicing.
- Work was cancelled after the invoice went out.
What happens to the balance
A credit note carries a balance you can spend, and there are exactly two places it can go: applied against an open invoice for the same customer, or refunded.
Applying draws the balance down by the amount used rather than consuming the whole note, so a large credit can be spread across several open invoices over time. Each application is capped at the smaller of the two amounts, which is the arithmetic doing its job.
Why not just edit the invoice
Because your customer has a copy of it. If invoice 1043 was 5,000 when they received it and 4,200 when their auditor looks at it, that is a discrepancy nobody can explain. The credit note leaves both documents intact and creates a third that explains the difference. Tax authorities in most jurisdictions require this rather than prefer it.
Refunds
A refund is the cash movement. It usually follows a credit note but does not have to.
Here is the part that catches people out in almost every accounting system: recording a refund is not the same as sending money. When you mark a credit note as refunded in your books, you are creating the accounting record of a refund. The funds move through your bank or through your payment provider’s own dashboard, as a separate act.
This surprises people who expect a refund button to reverse a card charge. Gateways do offer that, but it happens in the gateway, and your accounting system records that it happened.
Credit or refund
- Ongoing relationship? A credit note is usually better for both sides. No bank fees, no delay, and it applies automatically against the next invoice.
- Relationship ending, or the customer asks? Refund. Holding a credit balance for someone who will never buy again is a liability that never resolves.
- Consumer sale under distance-selling rules? Check the rules. In many jurisdictions a customer exercising a statutory right to cancel is entitled to money back rather than a credit.
Debit notes
A debit note runs the other way. It is issued by the buyer to tell a supplier that the amount billed was too high and that the buyer expects a credit.
In practice a debit note is a formal request. The supplier responds by issuing their own credit note, and that credit note is what actually adjusts the accounting. Some businesses skip the debit note entirely and simply ask, which works until the amounts get large enough that someone wants the request in writing.
On your books, the credit you receive from a supplier is a vendor credit, and it behaves like a credit note in reverse: a balance you can apply against an open bill from that supplier, or take as a cash refund.
The tax point nobody mentions
Where you charged tax on the original invoice, the credit note has to carry the corresponding tax adjustment. A credit note that adjusts the net and leaves the tax alone will misstate your tax return.
Most jurisdictions also require a credit note to reference the original invoice. It is good practice regardless, because it turns two documents into a story anyone can follow.
How Invoice Crowd handles all three
A credit note can be raised on its own or created straight from the invoice you over-billed. Creating it from an invoice replicates the customer, the line items and the totals under a new CN number, with an opening balance equal to the amount credited.
From there the balance goes one of two ways. Apply it to an open invoice for the same customer, and the invoice due, the credit balance and the ledger trail update together. Or record a refund.
Four boundaries worth knowing before you rely on it:
- Same currency only. A credit note and the invoice it is applied to must use the same currency, with no conversion during application, so an amount typed into the apply form can never be interpreted at an unintended rate.
- Refunding records the refund, it does not move the money. No payment gateway is called. Pay the customer through your bank or your provider’s dashboard, then record it.
- Delete stays available while a balance remains, including on a note already partly applied or partly refunded. Once the balance reaches zero the note reads Closed and delete disappears.
- No payment methods tab. The editor hides it, because a credit is not a document you collect money on.
On the purchase side, vendor credits are separate screens with their own behaviour, and the credit note refund action will not act on one. Raise a vendor credit from the bill and either apply it against that bill or record it as a cash refund, which runs as one locked transaction.
Customers see their credit notes in the customer portal as read-only, subject to the portal permissions you set.
A decision tree
- Did you over-bill a customer? Credit note.
- Do they want the cash back rather than a credit? Credit note, then record the refund after you have actually paid them.
- Did a supplier over-bill you? Ask for a credit, formally with a debit note if the amount warrants it. Record what you receive as a vendor credit.
- Has the invoice not been sent yet? Then none of this applies. Edit the draft.
Frequently asked questions
Is a credit note the same as a refund?
No. A credit note acknowledges that you owe a customer money back and creates a balance they can apply against future invoices. A refund is the act of actually returning the money. A credit note can lead to a refund, but most credits are applied to the next invoice instead, which suits both sides better when the relationship continues.
Can I just edit or delete the original invoice instead?
Not once it has been sent. Your customer holds a copy, and an invoice that says one thing on their side and another on yours is a discrepancy nobody can reconcile. Most tax authorities require a credit note rather than an amended invoice. If the invoice is still a draft and has never left your system, edit it freely.
Does refunding a credit note send money back to the card?
Not in Invoice Crowd. Refunding a credit note records the refund and does not move funds, and no payment gateway is called by the action. Pay the customer through your bank or through your payment provider dashboard, then record the refund so the books match what happened.
Can one credit note be applied to several invoices?
Yes. Applying draws the balance down by the amount used rather than consuming the whole note, so a credit can be spread across several of the same customer open invoices. Each application is capped at the smaller of the credit balance and the invoice due.
Can I apply a credit note to an invoice in a different currency?
No. In Invoice Crowd a credit note and the invoice it is applied to must use the same currency, and no conversion is performed during application. The restriction exists so that an amount typed into the apply form can never be silently interpreted at an unintended exchange rate.
What is a vendor credit and how is it different?
A vendor credit is the purchase-side equivalent: a credit a supplier has issued to you, which you can apply against an open bill from that supplier or take as a cash refund. It lives on its own screens in Invoice Crowd and the credit note refund action will not act on one, because the two run in opposite directions through your ledger.
